File:Copper alloy terminal from a Celtic-style pennanular brooch 6th-7th century AD (FindID 915162).jpg

English: Fragment of a copper alloy penannular Celtic-style brooch with a zoomorphic terminal dating to the late 8th or 9th century AD.The terminal is sub-triangular in plan tapering to a broken edge at the start of the hoop.On the back of the terminal there is a circular indentation which may have traces of silver or tinning.The upper surface of the terminal has relief decoration comprising a central ring around the outside of which are three smaller rings (evenly spaced) joined by relief arcs.It is possible that the cells these shape create could have been filled with coloured glass or enamel.However no traces survive.

While only a fragment survives of this brooch its Irish origins are clear and it shares features with some noted Irish brooches, in particular, the 'County Cavan' brooch (Ó Floinn in Youngs, 1989, No. 73) Both brooches have a circular central setting on their terminals around which are three crescentic ribs. A still more striking link is the animal-head, viewed from above, with herring-bone markings, a feature which appears on both brooches and is well known on Irish metalwork of the period, also appearing on the pin head and chain attachment on the 'Tara' (Bettystown) brooch (Ó Floinn in Youngs, 1989, page 77). Ó Floinn expressed some caution in dating the County Cavan brooch but suggested that it was produced in the eighth or early ninth century.

The surface of the fragment has a dark green patina but is pitted.
